  2. Remove the pits from the prunes.

Assemble the loaf

  2. Line a baking dish with the soaked bread.

  3. Add the prunes and a little marmalade on top.

  4. Cover with another layer of soaked bread.

  5. Tie a piece of buttered paper over the dish.

Bake

  1. Bake for 1 hour at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Prunes
Provide the main filling, with moisture and a soft, sweet texture once cooked.
Bread
Forms the layers that soak up butter and hold the fruit together as the loaf sets.
Clarified butter
Coats the bread, adding richness and helping it brown and crisp in the oven.
Port wine
Adds depth and aroma to the prunes while they simmer.
Brown sugar
Adds sweetness and helps the prunes turn soft and glossy as they cook.

The step that matters

Soak the bread in clarified butter. Bread that is soaked evenly absorbs fat and softens, so every layer bakes moist and rich. Dry patches stay tough and can burn at the edges.
